A cyberattack on Health Sciences North in Sudbury, Ontario, yesterday has reportedly disrupted multiple systems at 24 of the Canadian health provider’s hospital facilities in the northeastern part of the province.

Dominic Giroux, CEO of Health Sciences North, said the virus that caused the incident “is not captured by the current anti-virus tools that are available on the market,” the CBC News has reported. “As a safety measure, we put all our systems on downtime to avoid any contamination of the systems at HSN.”

The epicenter of the infection reportedly took place in HSN’s cancer program system, but the downtime also is affecting electronic medical records, medical imaging systems and email and office productivity software.

Fortunately, Giroux said there was no data breach and the data was not corrupted by the malware.
